Custom object to select specific mail merge object

[sness]

Is it possible to have a custom object that will select a specific mail merge template for export?  I can display the Export button (master_btnExport), but was hoping to expand on the function to make it easier for end user as we have a dozen or so templates.

TIA

@SureshMGB You'll have to look at the Job log for that log reference id if you're on-prem or open a ticket with support to get the entry.

The last time I checked the custom object still works.  Make sure you have all the values for the last three variables are correct.
